#64 – Escape Sequences in String Literals

C# allows embedding special (often non-printable) characters into a string literal using an escape sequence.  An escape sequence is a series of characters that begins with a backslash (\), followed by one or more letters or digits.

Here’s an example of embedding several newline characters into a string, so that it’s printed on three different lines.

 Console.Write("First line\nSecond line\nThird line\n");     // 3 lines

Full list of escape sequences in C#:

  • \a  –  Bell (alert)
  • \b  –  Backspace
  • \f  –  Formfeed
